H Control Hybrid provides dual performance within a single product. It offers a vapour control layer and insulation, allowing a reduction in the number of installation steps whilst reducing the thickness of the main insulation to achieve the same required uValue. This H Control Hybrid is a reflective vapour control layer with a built-in thermal performance for use on the warm side of any insulation material, behind the internal finish in roofs, walls and ceilings. It can be used in conjunction with any type of insulation. With minimal air permeability and excellent watertightness, it is airtight and watertight.
